CAR-AXLE.

SPECIFICATION formingpart of Letters Patent No. 264,474, dated September19, 1882.

' Application filed May 22, 1882. (No model.)

split hearing, which supports and carries rigidly secured to it the mainhearing, which works in the usual axle-box, the said split hearing beingclamped by the wheel -hub; and in minor details of construction, all ofwhich are more fully set forth in the following specification and shownin the accompanyingdrawings, which form part thereof.

The object of my invention is to facilitate the passage ofrailroad-wheels under cars around curves, and to overcome the resistanceoccasioned by the circumferential slipping on the rails by the wheels,as is the case with rigid wheels and axles now in general use.

In the drawings, Figure l is a sectional elevation, on line 00 m, ofpart of my improvement.

Fig. 2 is a side elevation of same, looking in a line with the center ofthe axle. Fig. 3 is an elevation of the center part of. the axle. Fig. 4is a perspective view of one-half of the core or split bearing. Fig. 5is a cross-section of the axle on line 3 y, and Fig. 6 is an end view ofthe core.

The wheels L may be of any desired pattern, but are made larger at thehub K, this extra size of hub being necessary to receive the core orsplit bearing E, which is a cylindrical iron or steel bed, made in twohorizontal halves, with edges planed or grooved, as at e, to fit eachother, and which, when placed together, form a round core adapted to bepressed by hydraulic or other power into the hub K, the flange or rim Earresting the hub at the proper place. The internal formation of thiscore E is shaped to fit the collars O J and bodies of hollow axle A andend section, 1, by being provided with annular grooves G F and apertureH. The collars B and O are heated and shrunk on the ends of the hollowaxle or center part, A, which may be turned up to receive them.

The axle, broadly, is divided into three secwrought-iron collars O B,that are shrunk on it,

keep the wheels L to gage and in proper position.

The two iron or steel collars on each end of the axle A are arranged oneoutside and one inside the core E, as shown in Fig. 1.

There are four smallscrew-plugs, M, in different parts of the axle A,said plugs being arranged equidistant about the circumference of thesaid axle, and are used to fill the axle with oil, and by theirarrangement one of the plugs will always be up.

The ends of the hollow axle A are closed by screw-plugs D, and insidethe screw-plugs and through the pipe forming the axle A, at each end,are bored holes 01, through which the oil flows to lubricate the axleinside the cores E.

The end sections, I, of the axle proper are made of steel orwrought-iron and rest in the cores E, by which they are firmly clamped,the ends projecting and forming the bearings t'for the brasses of theaxleboxes, which are they same as are now in general use. These endsections, I, of the axle are firmly secured to the cores E and preventedfrom turning therein by pins 2" of sufficient length and size, whichpass through the outside of the core E into the end sections, 1. Thesepins are put in place before the cores are pressed into the wheel, andtherefore when the said cores are in position they cannot work out.

The bearingt' is lubricated in the same manner as are the bearings inthe rigid axle now in general use, and, in addition thereto, a channel,1, is bored through the center of each end section, I, of axle, by whichoil or other lubricant may pass to lubricate the independent axle Ainside the core E. The inner ends of these end sections, I, are providedwith solid collars or flanges J, which fit into the annular grooves F inthe cores E, and by which they are prevented from working out.

Between the end of the center section, A, and end sections, I, of axleare steel disks N, which are used to prevent any undue wear of theseparts.

I do not limit myself to the exact construction of the parts shown, asthey may be moditied in various ways without departing from myinvention.

The collars B and ends of cores E are provided with rims b e, whichprevent any escaping oil from spreading upon the axle, collars, hubs, orcores.

If desired, one end of axleA may be rigidly attached to one wheel, L,and have a bearing, 1', formed on its end.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is- I 1.- In a car-wheel axle, two car-wheelshaving bearings upon theironter sides for the axleboxes of the car, incombination with a center part or axle made hollow and loosely jonrnaledin each of said car-wheels, said hollow axle being provided with meansto admit a lubricant,

- and holes to allow said lubricant to flow from said axle to itsjournals in the wheels, substantially as and for the purpose specified.

2. An axle made of a center and two end sections, in combination withsplit cores arranged to firmly clamp the end sections and form bearingsfor the center sections and wheels, the hubs of which clamp the twoparts of the cores together, substantially as and for the purposespecified.

3. The center part, A, provided with collars 0 upon its ends,iucombination with split cores E, having grooves G F, end sections, I,having bearings i, and wheels L, having hubs K, substantially as and forthe purpose specified.

4. The center part, A, made hollow, and provided on its ends withcollars and plugs, split cores E, having grooves GE, end sections, I,having bearings i, and wheels L, having hubs K, substantially as and forthe purpose specified.

5. The hollow center part, A, closed on its ends and provided with holes(I, collars B U, and plugs M, in combination with cores E, made in twoparts, and having grooves G F, end sections,I,having flange J, hearingsi, and channel I, and wheels L, having hubs K, substantially as and forthe purpose specified.

6. The combination of hollow axle A, having collars B 0, closed endplugs D, and holes d, cores E, having grooves G F, and made in halves,end sections, I, having flanges J, and bearings i, disks N,and wheels L,having hubs K, substantially as shown.

7. A car-wheel axle made hollow and provided with a series of closedapertures arranged about its circumference to fill it with a lubricant,substantially as and for the purpose specified,in combination with loosewheels up on one or both of its ends.

In testimony of which invention I hereunto set my hand.
